These lands contain many traces of the Andrade family, mediaeval Galician nobility. The As Mariñas area in A Coruña province contains a wealth of cultural heritage, of which the castle of A Nogueirosa is a highlight.

Constructed in 1369 on the orders of Fernán Pérez de Andrade, the site chosen was a rocky hill known as the Pena de Leboreiro. This was for defensive reasons and because of its vantage point over the mouth of the Eume river and the Ares estuary, it watched over the town of Pontedeume, one of the main feudal domains of the Andrade family.

The castle's keep is well conserved to this day. The square, 20-metre high tower now makes an excellent observation platform.
